The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the thermostat calls for cooling, the contactor closes and delivers line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't turn on at all, runs continuously without shutting off, or shows signs of pitting and burning on the contact points.
